Extract the contents of the zip file and navigate to the adbfastbootmac directory [Note: This package works on macs, if you are using Linux or any other operating system, a simple online search should help you figure out how to get adb and fastboot]

Make sure that the device has at least 50% battery power before commencing with the process.

Since the Keon has only one soft touch button on it, it is mapped to the back functionality. If you want to use all three default Android soft-buttons, the easiest way to do that would be to install the “SoftKey Enabler” app from the Android Play Store.

SWITCHING BACK TO FIREFOX OS

If you now want to switch back to Firefox OS, all you need to do now is as follows:-

Turn off your device.

Press the power and the volume up buttons of the Keon at the same time to boot into the Team Win Recovery image.

Tap ‘Restore’ and select the backup file created earlier during the Android setup, and confirm.

Once the process completes, you should be able to use Firefox OS again! 🙂

DISCLAIMER: Please note that the steps I’ve mentioned here are what I followed to try out Android on a couple of my Keons. These steps involve flashing the device, hence involve a very real risk of ending up with a bricked [dead] phone. As such, go about the process at your own risk. I’m in no way liable for any unforeseen results coming out of this process.
